Family Guy and American Dad are marketed as family shows?
That's news to me. I just can't get into The War At Home. I think I've seen it twice and each time I only could last about 15 minutes into the show.
I know as far as parental blocks/montoring, there is the V-chip too, but most cable providers (I know mine does) have built in monitoring systems for parents to use that will block certain channels or shows. So its not that hard for parents to monitor what their kids watch.
